“Cites per paper” is a two-year cited-by rate computed from OpenAlex. It is not a Clarivate Journal Impact Factor — we neither compute nor license that metric (how the two differ). Citation rates differ enormously between fields, so compare within a discipline. What the other figures mean: journal quartile, SJR, h-index and article processing charge.

Scimago Journal Rank 2025
In the Scimago Journal Rank 2025 edition, American Journal of Science is Q1 in Earth and Planetary Sciences (miscellaneous) (#37 of 377 journals).

The quartile is the one Scimago prints for each category. Rank is the journal's position by SJR among the journals Scimago lists in that category (#1 is the highest); “—” means we hold no rank consistent with that quartile. The document count is what Scopus indexed that year, which can be lower than a journal's full output. Source: SCImago Journal Rank 2025 edition, from Scopus data (scimagojr.com, CC BY-NC).

Frequently asked
Is American Journal of Science a predatory journal?
Our screening does not flag American Journal of Science. That is not a guarantee of quality — it means the venue is not on Beall's archive (frozen since 2017) and does not match our name-pattern heuristic. It is listed in Scopus, Web of Science, PubMed, which is a positive signal.
Is American Journal of Science indexed in Scopus or Web of Science?
Per our venue index, American Journal of Science appears in: Scopus, Web of Science, PubMed. Index membership changes over time — confirm on the index's own site before relying on it.
What is the impact factor of American Journal of Science?
Papers in American Journal of Science are cited about 3.1 times each within two years of publication, and Scimago places it in Q1, with an h-index of 239. Those are the open equivalents: the Clarivate Journal Impact Factor is a proprietary metric we neither compute nor license, so we show the two-year citation rate and Scimago quartile instead — they answer the same question of how heavily the journal is cited. A citation rate is a property of a field as much as of a journal.
What Scimago quartile is American Journal of Science (Q1, Q2, Q3, or Q4)?
In the Scimago Journal Rank 2025 edition, American Journal of Science is Q1 in Earth and Planetary Sciences (miscellaneous) (#37 of 377 journals). Quartiles split the journals in a subject category into four equal groups by SJR, so Q1 is the most-cited quarter and Q4 the least; American Journal of Science is cited about 3.1 times per paper over two years, with an h-index of 239.
What is the Web of Science (JCR) quartile of American Journal of Science?
The Web of Science quartile comes from Clarivate's Journal Citation Reports (JCR), a proprietary product we neither license nor compute — so we cannot state a JCR quartile for American Journal of Science. The open equivalent is its Scimago quartile, Q1, derived from Scopus citation data. Because JCR ranks against Web of Science and Scimago against Scopus, the two can differ, so check Clarivate's site directly if you need the JCR quartile specifically.
Is American Journal of Science open access?
Our index records its access status as "hybrid". Where this is derived from publisher-level signals rather than works-level data it is a heuristic, so confirm on the journal's own site — particularly if an article processing charge matters to you.
